MoultingYAML: a Scala wrapper for SnakeYAML

Hi!

I wanted to share a little Scala wrapper for SnakeYAML, a YAML parser 
and emitter in Java. Its interface is heavily inspired on spray-json's 
[1] type-class based (de)serialization. It's available on GitHub [2] 
under the MIT license. Detailed usage instructions are available at the 
project's README: 
https://github.com/jcazevedo/moultingyaml/blob/master/README.md.

[ANN] No Carrier, a new Scala-based GitHub bot to close abandoned issues

I am very excited to announce the public release of version 1.0.0 of "No
Carrier" !

"No Carrier" is a tool to automatically close old GitHub issues that
have been abandoned by the user who opened the issue (i.e. issues where
the project's team was waiting for more information from the reporter,
but never got a response in a reasonable amount of time).
No Carrier is written in Scala, requires Java 8+, and is released under
the MIT License.
It was written for, and is used by, the Bootstrap project
(http://getbootstrap.com ), to help manage our stream of incoming
issues. You can see the bot in action at
https://github.com/twbs-closer?tab=activity

For more info, check out the GitHub repo:
https://github.com/twbs/no-carrier

A prebuilt fat JAR can be found on
https://github.com/twbs/no-carrier/releases/tag/v1.0.0

Thanks,
Chris Rebert

[Play 2.4 Sample] Amazon Wishlist API demo project - Play, JSoup, React

I've just released a new version of the Amazon Wishlist API that I originally released two years ago.



Project demonstrates:
* Various Scala features
* Using React/JSX/Harmony
* Using JSoup in Scala for content scraping
* Using Play 2.4 runtime DI
* Using play-json
* A basic Akka agent
* Asynchronous http client (spray-client)
* Using MVstore
* Using play-json
* Using SBT AutoPlugins
* Creating an SBT multiproject build
* Using the scala-async library
* Using ScalaTest
* Programming without lazy-vals (the previous version had far too many)
* Recursive futures (e.g. fetch a series of pages without knowing how many there will be)

This will most likely benefit an intermediate Scala developer, and possibly a keen beginner.

Warm Regards,
William

CurioDB: A Distributed & Persistent Redis Clone

Hi all,

I just wanted to share a project I've been working on over the last 6 months. I've called it CurioDB [1], it's a clone of Redis [2] that I've built in under 1000 lines of Scala/Akka. It makes use of Akka's persistence and clustering to overcome some of the shortcomings of Redis [3].

It's my first real Scala project. I started building it as a learning exercise, but found the experience so enjoyable that I took it much further than I originally thought possible of myself. Hopefully someone finds it useful and sees it as a showcase for how trivial Akka makes building distributed systems.

CFP: AGERE! <at> SPLASH 2015 - ACM SIGPLAN Workshop on Programming based on Actors, Agents, and Decentralized Control

Hi, all,

Contributions to the below workshop are especially welcome from the Scala community.

Cheers,
Philipp

Call for Papers:
AGERE! <at> SPLASH 2015 - http://soft.vub.ac.be/AGERE15

5th International ACM SIGPLAN Workshop on Programming based on Actors, Agents, and Decentralized Control

Held at SPLASH Conference http://2015.splashcon.org/
Pittsburgh, Pennsylvania, USA - October 25/26, 2015

=====  Introduction  =====

The fundamental turn of software to concurrency and distribution is not only a
matter of performance, but also of design and abstraction. It calls for
programming paradigms that, compared to current mainstream paradigms, would
allow us to more naturally think about, design, develop, execute, debug, and
profile systems exhibiting different degrees of concurrency, autonomy,
decentralization of control, and physical distribution.

AGERE! is an ACM SIGPLAN workshop dedicated to focusing on and developing
research on programming systems, languages and applications based on actors,
agents and any related programming paradigm promoting a decentralized mindset
in solving problems and in developing systems to implement such solutions.

The workshop is designed to cover both the theory and the practice of design
and programming, bringing together researchers working on models, languages
and technologies, and practitioners developing real-world systems and
applications.

More info about the specific topics can be found on the AGERE! 2015 website.

===== Contributions =====

The workshop welcomes three main kinds of contributions:

(1) mature contributions, to be published in the ACM Digital Library as an
    official ACM SIGPLAN publication;

(2) position papers and work-in-progress contributions, to be discussed
    during the event and included in the informal proceedings;

(3) demos that will be presented and discussed during the event.

Info about the format and the page limits can be found on the AGERE! 2015
website (http://soft.vub.ac.be/AGERE15).

===== Special Issue =====

A special issue on a reference journal [*] will be organized with the extended
and revised versions of the best papers accepted and presented at the workshop.
This special issue follows a previous one published in Science of Computer
Programming (best papers from AGERE! 2011 and 2012) and a twin special issue
published in Computer Languages, Systems and Structures and in Concurrency and
Computation: Practice and Experience (best papers from AGERE! 2013 and 2014).

[*] Contacts are ongoing: targets include "Computer Languages, Systems and
Structures" (Elsevier), "Concurrency and Computation: Practice and Experience"
(Wiley), "Software: Practice and Experience" (Wiley), "Journal of Software and
Systems" (Elsevier), and "Science of Computer Programming" (Elsevier).

-----------------------------------------------------------------
SCOPE

GPCE is a venue for researchers and practitioners interested in techniques
that use program generation, domain-specific languages, and component
deployment to increase programmer productivity, improve software quality,
and shorten the time-to-market of software products. In addition to
exploring cutting-edge techniques of generative software, our goal is to
foster further cross-fertilization between the software engineering and the
programming languages research communities.

-----------------------------------------------------------------
TOPICS OF INTEREST

GPCE seeks contributions on all topics related to generative software and
its properties. Topics of interest include, but are not limited to:

Generative software
* Domain-specific languages (language extension, language embedding,
  language design, language theory, language workbenches, interpreters,
  compilers)
* Product lines (domain engineering, feature-oriented and
  aspect-oriented programming, pre-processors, feature interactions)
* Metaprogramming (reflection, staging, partial evaluation), Type
  systems, Program synthesis
* Implementation techniques and tool support (components, plug-ins,
  libraries, metaprogramming, macros, templates, generic programming,
  run-time code generation, model-driven development, composition tools,
  code-completion and code-recommendation systems)

Practical Applications and Empirical evaluations
* Empirical evaluations of all topics above (user studies, substantial case
  studies, controlled experiments, surveys, rigorous measurements) 
* Application areas and engineering practice (Cloud Computing, Internet of
  Things, Cyber Physical Systems, Mobile Computing, Software Defined
  Networking, High Performance Computing, Patterns and Middleware,
  Development methods)

Properties of generative software
* Correctness of generators and generated code (analysis, testing, formal
  methods, domain-specific error messages, safety, security)  
* Reuse and evolution
* Modularity, separation of concerns, understandability, and
  maintainability 
* Performance engineering, nonfunctional properties (program optimization
  and parallelization, GPGPUs, multicore, footprint, metrics)

We particularly welcome papers that address some of the key challenges in
the field, such as,
* synthesizing code from declarative specifications
* supporting extensible languages and language embedding
* ensuring correctness and other nonfunctional properties of generated code
* proving generators correct
* improving error reporting with domain-specific error messages
* reasoning about generators
* handling variability-induced complexity in product lines
* providing efficient interpreters and execution languages
* human factors in developing and maintaining generators

GPCE encourages submissions about empirical evaluations and applications of
generative software, and such papers will be given special consideration
during reviewing.

-----------------------------------------------------------------
GPCE SUBMISSION GUIDELINES

Research papers: 10 pages maximum (ACM SIGPLAN style)

Research papers should report on original and unpublished results of
theoretical, empirical, conceptual, or experimental research that
contribute to scientific knowledge in the areas listed above (the PC chair
can advise on appropriateness)

Tool demos and short papers: 4 pages maximum (ACM SIGPLAN style).

The goal of short papers is to promote current work on research and
practice. Short papers represent an early communication of research and do
not always require complete results as in the case of a full paper. In this
way, authors can introduce new ideas to the community, discuss ideas and
get early feedback. Please note that short papers are not intended to be
position statements. Short papers are included in the proceedings and will
be presented with a shorter time slot at the conference.

Tool demonstrations should present tools that implement generative
techniques, and are available for use. Any of the GPCE topics of interest
are appropriate areas for tool demonstrations, although purely commercial
tool demonstrations will not be accepted. Submissions must provide a tool
description of 4 pages in SIGPLAN proceedings style (see above) and a
demonstration outline including screenshots of up to 4 pages. Tool
demonstrations must have the words "Tool Demo" or "Tool Demonstration" in
the title, possibly appended in parenthesis. The 4-page tool description
will, if the demonstration is accepted, be published in the proceedings.

-----------------------------------------------------------------
COMLAN SPECIAL ISSUE SUBMISSION GUIDELINES

The special issue will publish GPCE'15 papers by invitation from the
guest editors, is closed to papers outside the conference, and will
only include top-ranked papers from GPCE'15 (based on the GPCE'15
review, see scope and topics of interest, above).  The special issue
will be published by Elsevier in Computer Languages, Systems and
Structures (COMLAN):
